Circulatory System

Cockroaches do have circulatory systems, they are are open circulatory systems

it's hemoglobin. It holds and transports oxygen. oxygen is hydrophobic and so can't enter your blood. It has to be carried by hemoglobin.

No. Your body can dilate blood vessels so more blood reaches an area, or constrict or shunt it away from an area when more blood is not needed. It all depends on what the body requires for any given situations; your surroundings always change, so your body must always react to adapt to that change. For example, when you eat your body concentrates more blood to your disgestive system in order to process and absorb the incoming nutrients. In a stressful or dangerous situation, your body secretes the hormone adrenaline (the "fight or flight" hormone) and one of its effects is that less blood is concentrated to your digestive system.

The cardiovascular system is generally divided into the heart and the blood vessels. However, another division could be between the pulmonary circulation and the systemic circulation.

Another delivery option is transtracheal oxygen therapy, which involves a small flexible catheter inserted in the trachea or windpipe through a tracheostomy tube.

== == It is stressed, but will adapt.

The circulatory system cannot work as efficiently, because there is less oxygen and CO2. After being at a high altitude for a long time, the body will adapt. It will produce more red blood cells so that it can pick up more oxygen, since less oxygen is carried by each hemoglobin at high altitudes.

He discovered digitalis and neccesary information to helping cure the heart today. HOPE THIS HELPS

Yes..

yea its an open circulatory system

The myocard (cardiac muscle), the muscle that makes your heart pump, needs oxygen to function. This oxygen is distributed through the blood that flows in the coronary arteries, which lie around the cardiac muscle. When there is not enough oxygen in your blood, the cardiac muscle does not get enough oxygen to fully function and your heart will not be able to function, over time. This starts at about 3 minutes after stopping to get oxygen.

No. The circulatory system does transport various gasses around the body but the main gas the body needs is Oxygen (and not 'fresh air'). The blood transports breathed in Oxygen from the lungs into the tissues and organs and transports waste gasses such as carbon dioxide from the tissues and organs to the lungs to be expelled when breathing out. The circulatory system's job is transportation of the gasses to and from where they need to go in the body.

oxygen

Without these systems, we wouldn't be able to breathe or to pump blood throughout our body. We need these systems in order to stay alive.

By diffusion across a capillary wall.

the role of the circulatory system is to transport oxygen and nutrients to all the cells in that one organism

Your blood is never truly dexoygenated, but as it delivers oxygen to tissues the saturation of oxygen gets lower. When the blood reaches the alveoli of the lung oxygen diffuse from the higher concentration of the air to the lower concentration of the blood, where most of it binds to hemoglobin molecules.

In circulatory is the u a e i o

In the nervous is the brain for magimbu

Vena cava --> Right atrium --> Tricuspid valve--> Right ventricle --> Pulmonary artery --> Pulmonary semilunar valve --> Lungs --> Pulmonary vein --> Left atrium --> Mitral valve --> Left ventricle --> Aortic semilunar valve --> Aorta --> Carotid artery, Brachial artery, femoral artery, etc... --> Arterioles --> Capillaries --> Venules --> Veins --> Vena cava

YES

If your asking about primary absorption in digestion and the absorption of nutrients into the body, then primary absorption is the first (primary) place in the body where nutrients are absorbed. In humans this takes place in the small intestines after the food has been broken down in the stomach and passed on to the small intestine.

The circulatory system transport the nutrients that help build up other organs.If for some reason the circulatory system get disordered,the nutrients wouldnt reach the other organs which will cause the other organs to malfunction and eventually stop doing their specific work. Wrote By: LB
